[MlMt] How can I create a Smart Mailbox with all emails I have sent?

[leo]

Hi all, I would like to create a Smart Mailbox containing all emails I 
have sent.

I have tried a condition like  `“From -> Address“ contains 
“<my email address>“`:

But with this the Smart Mailbox contains spam which pretends to be sent 
from my address as well.

Is there a mail header which says „_This message was really sent from 
this particular SMTP server_“ or similar?

Many thanks,
Leo
